Just got a new Probook 4540s and cannot get the on/off function of the touchpad to work. There is a small dot in the upper left corner of tochpad. User guide says to double tap it to turn on and off touchpad. Doesn't work. I then went to driver download and got the latest synaptics drivers. Still doesn't work. What am I doing wrong?

i just bought a probook 4540s from my local school because they where getting rid of there old computers and it wont let me even get past the administrator login so i can change the settings and there is no f11 option. please help me figure out how to get it taken care of because im planning on giving it to my sister as soon as i can get it back to factory settings.

Attempted to up-date to Windows 10. Couldn't do it. Microsoft (MS) Tech tried to do it and couldn't do it. It seems there are some security tools that must be removed as they are incompatable with Windows 10. MS tried to remove and couldn't do it. He said they were on the mother board and when he tried to remove them they just kept coming back so once again he couldn't do it. He said contact HP and they could do it. Unable to find anybody at HP that can do it. As you can see nobody can do it so I guess it just cannot be done. That is unless some fine person out there has discovered a way to do it. If thats the case please tell me ho wo do it.

Hi, I ve been using a Probook 4540s from the year 2013. Today while I was reading a book (offline) my display stated to give some unclear pictures. Pictures were moving up and down and gave overlapped scences. Please refer the attached GIF or click here to understand the scenario (Link to GIF https://giphy.com/gifs/QzGO4cPW76wUM ) I updated the Intel Video Driver also but it could not solve the issue. Then I restarted the computer. During the boot process I realized it is not a software issue as the dispaly was acting the same. I feel this is like a hardware issue in the display or the ribbon cable.Please look at this and help me solve the case. Highly appreciate your coordiantion on this. Thanks,Isuru Reference Image

HiI tried to update to W10 and failed with OXC 1900200 which suggests a compatibility issue. It is unclear on the HP website if this model supports W10 - HP has not tested your PC model for upgrade to Windows 10.If your Windows 7 or 8 PC was manufactured before August 2013 or is running Windows XP or Windows Vista, HP cannot confirm it can be upgraded to Windows 10. Can anybody offer an advice if the 4540S supports the W10 upgrade and if so any advice on what may be causing the error. ThanksJohn

I am just wondering whether I can put a eGPU on my HP Probook 4540s to play some of the more modern games and some of the games that are a few years old now on something like high to ultra graphics. I'm thinking something along the line of a NVIDIA GTX 960 or 970ish. I actually even found some GeForce GTX 1050's at a cheaper price so is there a way I could connect something like that to this laptop. It would be cheaper then trying to save for an actual gaming rig at this time. Thank you for any replies its much appreciated.

I have a new ProBook 4540s notebook that I shut down over the weekend. I am not sure if I put it into hibernate, sleep, or what as I am still getting use to it. When I tried to turn it on (not plugged in) I got nothing. So I plugged in the power cord and hit the power button again. All it did was the LED above the cord plug blinked about 8 times and nothing else. I let it "charge" overnight and tried again in the morning. Nothing but a blinking LED. I Googled the problem and it said to take the battery out, unplug, and hold the power button down for 20 seconds. I plugged it back in but left the battery out, and still the same thing - flashing LED. HELP! Thanks.

Hey SBProBook,Do any other LEDs blink? Take a look at this document and let us know if you see any matches to these patterns:http://support.hp.com/us-en/document/c01443366

I just have a quick question that i have not been able to find online anywhere and am wondering if you can provide some resolution for me. When I access the BIOS by clicking the F10 key on my laptop when I boot it I get the below environment which seems to be what everyone gets Now my question is if there is anyway to access a more "user friendly" BIOS layout like every other laptop/computer has shown below. I find that I don't have access to every option on my laptop in the BIOS that is currently present and I have the F60 BIOS which is the most recent one but most things are grayed out and I can't change things like the RAM speed or anything like that so I feel like I actually have no control over my system

Hello! My ProBook 4540s was working fine until a half hour ago, when I unplugged it to move it and then attempted to plug it back in, and it stopped charging. When plugging in the power cord (that came with the ProBook when I bought it around 18 months ago), the light above the power jack (and no other lights) flashes white 9 times. I've tried following this fix I found on Google: 1. Turn off the notebook2. remove the battery3. remove the charging adapter4. press + hold the power button for 40 seconds5. insert the charging adaptor only6. press the power button and it supposedly continues but I get stuck at this point, because even plugged in, my ProBook won't start up without the battery in also. Is this a know problem/is there a fix for this?

I found that my Probook 4540s sometimes cannot boot. I have to use the trick applied to 4530s: remove battery, press power button for 40s, put the adapter. Sometimes the trick works, sometimes it doesn't. Is this a bios issue? Any solution for this?

Well did you try reseating the memory? Has the computer worked since you have upgraded the memory? Also are the memory chips the same speed? If your running two different speed chips it could cause this issue. ThanksSean

We have a Probook 4540S laptop runnung Windows 7 64-bit. We encrypted the machine using the HP encryption software that came with the laptop. After less than a week of use the use is getting the error "Windows Boot Manager - Windows failed to start. A recent hardware or software change might be the cause".I see the onscreen instructions to insert the Windows installation disk and run a repair. My question is, is this a valid suggestion to fix a laptop that has been encrypted, and if not is there a solution w/o having to reimage the machine?

I have three probook 4540s laptops. do they support uefi boot ? thank you

A:does probook 4540s support uefi ?

Hi, I have a Probook 4540s and it has UEFI functionality.Bios version F.60 I can choose in BIOS between 3 boot modes:LegacyUEFI Hybrid (With CSM)UEFI Native (Without CSM) I hope this answers your question.

I upgraded to Win 10 Pro from Win 7 Pro during the free upgrade period, at the time I had a 500 gig 5400 rpm hard disc, later I replaced the HD with an OCZ Vector 180 ssd, used the included copy of Acronis disc cloning software (i updated the Bios to the newest Version HP offfered prior to installing the ssd), now when I do a cold boot it gives me an error message saying no operating system found, if I go into the BIOS Setup menu then exit out of it without making any changes it goes ahead and boots normally. I can also do a warm boot (restart)it also reboots normally. I tried contacting OCZ support, they had several suggestions such as delaying the startup time 5 secnds, didn't do anything, increased it to 10 seconds with thes same results (OCZ said the ssd needed more time to initialize itself). After trying 6 or 7 of their suggestions they sent me a new drive, I had saved the original HD so I cloned it to the new ssd, got the same results, no cold boot. I've tried evey setting I can find in the BIOS, changed it from UEFI to Legacy boot with no results, disabled network booting, everything but Optical Disc, disabled Quick Boot, but nothing has changed. In Legacy mode it shows the internal hard drive to be the first thing to boot from, but that does nothing but say it can't find a bootable drive and then the option left is shut down the computer. Looking in the BIOS under Devices it doesn't show the ssd at all. There's no firmware update available for the ss... Read more

Luck_amit001 Hello;Allow me to welcome you to the HP forums! As far as I know, HP only supplies Windows drivers, not Linux. And since those are completely different OSs, you can not use Windows drivers in Linux. Also, for Linux support, since HP does not provide that, you would need to contact the appropriate Linux support form for the Distro that you are running. Here is the link for the Ubuntu Forums: http://ubuntuforums.org/Good Luck

Dear Customer, Welcome to HP Support Forum and we are glad to assist you. This is to inform you that all HP Business Notebooks such as Probooks or Elitebooks have more stringent security than consumer models infact they don't produce 'halt codes', the password cannot be derived from the Serial Number and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case. Please have a look at this link. http://forums.mydigitallife.info/threads/49497-HP-Probook-Elitebook-BIOS-Password-Reset-Utility 2. Please Contact HP Business Notebook support they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

I will buy a ProBook 4540s (Intel i5) very soon. At a lot of places on the Internet, it had been mentioned that it supports upto 8GB DDR3 RAM. But, on a details page at HP site, it had been mentioned as "16GB". So, I'm a bit confused here, though I guess that it might be 8GB. I want to know about this for sure. Thanks

Hi and welcome to HP support forum!You have to download the program for fingerprint configuration first.You can find it in the driver downloads section of your product searching with your product id.Choose your operating system (preferably win8 or win 7)Download "HP ProtectTools security manager (international)" under Software Security section.Install and open it, follow instructions and you're done.Happy Eve!

I bought my laptop about two weeks ago. Then first, I installed Windows 7 Professional 64 bit. I installed "HP Protect Tools" & could enroll all 20 fingers at once without any issue. Then recently, reinstalled the whole system with Windows 7 Ultimate 64 bit. Then, installed Protect tools & could enroll my two thumbs. But I couldn't enroll any other finger. For each other finger, first two confirmtions work properly. But at third, it always fails. I cannot think that this is an issue related to how I sweep the fingers. Because, then how do every first two confirmations get passed?. Hope anyone will help me to sort this out.

Dear Customer,Welcome and Thank you for posting your query on HP Support Forum It looks like you are not able to Power ON the Notebook and wanted to fix the issuePlease perform below shown steps to find out if this is a software or hardware issue:1. Remove all Peripherals and Cables, Disconnect them and try to Power ON the Unit 2. Check for LED Light Status and ensure Power Button spring action is normal 3. Swap with a known good Power Cord and Power Adapter 4. Incase no Adapter is available, Check if the Power Adapter is slightly warmNote: This will give us a hint that the Power Adapter might be fine 5. Do you know if the Notebook was in Battery or Power Adapter Mode when you used it for the last timeNote: Ensure there is no liquid spillage or Power Outage 6. Check if the AC Adapter Port is loose/broken Note: If the Notebook doesn't Power ON even with a known good Power Adapter this confirms the Hardware fault with System Board or the DC Power Circuit Hope this helps, for any further queries reply to the post and feel free to join us again **Click the 'Thumbs Up Button' to say Thanks** Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem.
